Daytona vs. Chorus 10 Speed(6 posts)

Daytona vs. Chorus 10 SpeedZag
May 22, 2001 4:16 AM
I am considering upgrading my Veloce triple components to Daytona or Chorus 10 speed. If I go with daytona, I can use the same bottom bracket as with the Veloce components. That would make swapping back to a triple a bit easier if I needed to.

What are the disadvantages of the wider Daytona bottom bracket vs. the Chorus bottom bracket?

The Daytona BB, with it's longer spindle length, won't be quite as rigid. It's a pretty cheap unit, and one of the things I like least about this component group. If I was going to upgrade only a few things on the group, I'd start with the crank and BB.

I much prefer the cartridge style chorus and record BB for ease of installation. Uses the same tool as the cassette lockring.

What about the shifting performance? The main reason I am considering upgrading my component, is the poor shifting of the Veloce triple. Specifically, the upshift from the middle ring to the big ring is quite slow. It quite often takes 1/4 to 1/2 revolution to shift (i.e. the chain slips for awhile before the chainring grabs a hold of it).

I have been tweaking the adjustment of the front derailleur for the better part of a year now. The shifting is much improved, but still not as good as I would like it to be.

I am concerned that part of the reason for the poor shifting is the wide bottom bracket. If that is the case, then the narrower Chorus bottom bracket should result in improved shifting. Is this correct?

There's nothing about BB width that would cause poor shifting. It could be the chainrings, the triple front derailleur design or adjustment, or the chain.

Poor shifting can result from poor technique. Be sure you maintain a decent cadence (80+) and don't shift under a high load.

Front shifting on the new 10 speed system is the best I've ever experienced. Highly recommended.

I've got a Y2K Daytona triple bike and a 2001 Chorus/Record 10 bike. I have to be somewhat 'deliberate' and slow with upshifts on the triple.... otherwise the chain will get thrown off the big ring. The 10 shifts muy bueno.

Also, the Daytona BB is relatively flexy (this is part of the problem with the thrown chains). I'm going to replace the BB with a stiffer and narrower BB. I think I can loose about 5-8 mm width on the BB and still not have an interference problem with the inner ring/chainstay.
